Home Data Platform · Last updated 25 August 2026
Home Data Platform is a private, personal project run by one household to organise that household's own financial records. It is not a commercial product, has no customers, and is not offered to the public.
The only people whose data this application accesses are the members of the household who have personally signed in and granted access to their own accounts. No other person's data is accessed, and access is never sought from anyone outside the household.
With the account owner's explicit consent, the application reads email in the owner's Gmail
mailbox that Google classifies as purchases and receipts, using read-only access
(gmail.readonly). It reads message contents only to extract purchase and receipt
details. It never sends, deletes, or modifies email, and it does not read messages outside the
purchases category.
Receipt and purchase information is used solely to help the household understand its own spending. All data is stored privately on hardware the household owns and operates. It is not sold, shared, transferred, or disclosed to any third party, and it is not used for advertising, profiling, or any purpose other than the household's own record-keeping.
This application's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Google account data is used only to provide the household-facing features described above and is never transferred to others except as required to operate those features on the household's own systems.
Data is retained only as long as it is useful to the household and can be deleted at any time by the household. A person may revoke this application's access to their Google account at any time from their Google Account permissions page, after which no further data is accessed.
Questions about this policy can be sent to the project owner at keithkam@gmail.com.
